CoalWalesUnited Kingdom

Uskmouth Power is a 230 MW coal power station in Wales, United Kingdom. Based on its capacity (estimated), it can supply roughly 287,828 homes (estimated). It ranks #78 of 2,751 United Kingdom power plants by installed capacity. In context, coal supplies about 0.1% of United Kingdom's electricity; the national grid averages 217 gCO₂/kWh (64.4% low-carbon) (2025).

~1,007,400 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

234,825passenger cars driven for a year
131,377homes' yearly energy use
16,790,000tree seedlings grown 10 years to absorb it

Estimated, not measured: from installed capacity at a typical 50% load factor × a typical coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

Local climate & thermal context

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 51.5°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 12% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 56/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
